Description

Technical Field

[0001] This utility model relates to the technical field of bearing seal ring skeletons, and in particular to a stamping die for a bearing seal ring skeleton. Background Technology

[0002] The bearing seal skeleton is a crucial component of the bearing seal ring, primarily used to improve sealing performance and extend bearing life. Bearing seal rings typically consist of an outer metal skeleton and an inner rubber ring. The metal skeleton provides structural support, while the rubber ring is responsible for the sealing function. The metal skeleton can be designed as a single layer or a double layer, depending on the application requirements.

[0003] In the existing technology, since the bearing seal ring skeleton is composed of a metal skeleton and a rubber ring, it is necessary to stack the metal skeleton and the rubber ring together during its production. Then, the metal skeleton and the rubber ring are pressed together by a punch to form a complete bearing seal ring skeleton. This method requires frequent alignment of the metal skeleton and the rubber ring to ensure the pressing effect of the bearing seal ring skeleton, which leads to low production efficiency of bearing seal rings. Utility Model Content

[0004] This application provides a stamping die for a bearing seal ring skeleton, which can be used to position the rubber ring so that the rubber ring is not damaged when the metal skeleton is pressed into the rubber ring. At the same time, it greatly improves the pressing efficiency of the metal skeleton and the rubber ring, thereby improving the production efficiency of the bearing seal ring skeleton.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A stamping die for a bearing seal ring skeleton, comprising:

[0007] The base has a top plate fixedly connected to each of its four corners by support columns, and a hydraulic press is installed on the top of the top plate.

[0008] The press-fit lower mold is fixedly connected to the top center of the base and is used to place the rubber ring;

[0009] The upper die is positioned above the lower die. The bottom of the upper die has a circular groove for accommodating the metal skeleton. The bottom of the groove has a limiting component for clamping the metal skeleton. The output shaft of the hydraulic press extends into the groove and is connected to a pressure block via a one-way bearing. The outer wall of the pressure block is connected to balls. The inner wall of the groove has a spiral groove for the balls to roll.

[0010] Furthermore, the limiting member includes a top block and a compression spring. The bottom of the side wall of the circular groove is provided with an installation groove, in which the top block is slidably connected. A compression spring is fixedly connected between the top block and the installation groove.

[0011] Furthermore, the side of the top block extending out of the mounting groove is machined with a spherical surface, and friction rubber is fixedly connected to the spherical surface.

[0012] Furthermore, the press-fit upper mold mainly consists of a positioning plate and a sleeve. The positioning plate is slidably connected to the output shaft of the hydraulic press, and the sleeve is rotatably connected to the output shaft of the hydraulic press. The top of the sleeve is connected to the positioning plate through a positioning element.

[0013] Furthermore, the positioning component includes a positioning block and a support spring. The top of the sleeve has a vertically downward-facing receiving groove, in which the positioning block is slidably connected. The bottom of the positioning block is fixedly connected to the receiving groove, and the bottom of the positioning plate has a positioning groove that engages with the positioning block.

[0014] Furthermore, the top of the press-fitting lower mold is provided with a placement groove for placing the rubber ring, and a positioning post for positioning the rubber ring is fixedly connected to the center of the bottom of the placement groove.

[0015] In summary, this utility model has at least one of the following beneficial technical effects:

[0016] 1. A stamping die for a bearing seal ring skeleton, by using an upper die and a lower die, can respectively position the metal skeleton and the rubber ring, thereby ensuring the pressing quality of the bearing seal ring skeleton. A circular groove for accommodating the metal skeleton is provided at the bottom of the upper die, and a pressure block is slidably arranged in the circular groove. When the upper die is pressed down, the pressure block is used to press the metal skeleton in the circular groove into the rubber ring, which can realize continuous production of bearing seal ring skeletons, thereby effectively improving the production efficiency of bearing seal ring skeletons.

[0017] 2. This stamping die for a bearing seal ring skeleton, through the setting of a one-way bearing, balls, and a spiral groove, allows the balls to roll in the spiral groove when the pressure block moves downward. At this time, the one-way bearing can rotate normally, ensuring that the pressure block can move downward normally to press the metal skeleton into the rubber ring. After the metal skeleton is pressed, when the output shaft of the hydraulic press moves upward, the pressure block will move upward, and the balls will reverse in the spiral groove. At this time, since the one-way bearing is locked and cannot rotate, the pressure block cannot rotate, thus preventing the balls from rotating in the spiral groove. The pressure block also cannot move upward in the circular groove. Therefore, the metal skeleton in the circular groove is always pressed tightly by the pressure block, while the bottom metal skeleton is blocked by the limiting component and cannot slide off. Therefore, when pressing the metal skeleton into the rubber ring again, after the upper and lower die of the pressing process come into contact, the bottom metal skeleton can be directly pressed into the rubber ring. This effectively avoids the pressure block resetting in the circular groove, which would cause a free stroke during the next metal skeleton pressing, affecting the pressing efficiency, thereby further improving the production efficiency of the bearing seal ring skeleton.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0025] Reference Figures 1-4 The present invention discloses a stamping die for a bearing seal ring skeleton, comprising:

[0026] The base 1 has a top plate 5 fixedly connected to each of its four corners by support columns 4, and a hydraulic press 6 is installed on the top of the top plate 5.

[0027] The lower mold 2 is fixedly connected to the top center of the base 1 and is used to place the rubber ring;

[0028] The upper die 3 is positioned above the lower die 2. The bottom of the upper die 3 has a circular groove 7 for accommodating the metal skeleton. The bottom of the circular groove 7 has a limiting member 8 for clamping the metal skeleton. The output shaft of the hydraulic press 6 extends into the circular groove 7 and is connected to a pressure block 10 through a one-way bearing 9. The outer wall of the pressure block 10 is connected to a ball bearing 11. The inner wall of the circular groove 7 has a spiral groove 12 for the ball bearing 11 to roll.

[0029] In this embodiment, observation Figure 1 It can be seen that a top plate 5 is fixedly connected to the top of the base 1 by support columns 4 at each of the four corners. A hydraulic press 6 is installed on the top of the top plate 5. The output shaft of the hydraulic press 6 passes through the top plate 5 and is fixedly connected to the upper mold 3. Then, a lower mold 2 for placing the rubber ring is connected at the center of the top of the base 1. The production of the bearing seal ring skeleton can be achieved by placing the rubber ring and the metal skeleton on the lower mold 2, and then driving the upper mold 3 to move down by the hydraulic press 6 to press the metal skeleton and the rubber ring together.

[0030] In order to ensure the pressing quality of the bearing seal ring skeleton, the metal skeleton and the rubber ring need to be aligned when stacked to ensure that the metal skeleton is completely pressed into the rubber ring. This will affect the pressing efficiency of the bearing seal ring skeleton.

[0031] Therefore, observe Figure 2 It can be observed that the bottom of the press-fit upper mold 3 has a circular groove 7 for accommodating the metal skeleton, and the bottom of the circular groove 7 is provided with a limiting member 8 for clamping the metal skeleton. The output shaft of the hydraulic press 6 extends into the circular groove 7 and is connected to a pressure block 10 through a one-way bearing 9. The outer wall of the pressure block 10 is connected to balls 11, and the inner wall of the circular groove 7 has a spiral groove 12 for the rolling of the balls 11. Figure 1 It can be seen that the top of the press-fitting lower mold 2 is provided with a placement groove 18 for placing the rubber ring, and a positioning post 19 for positioning the rubber ring is fixedly connected at the bottom center of the placement groove 18.

[0032] When it is necessary to produce the bearing seal ring skeleton at this time, first prepare the metal skeleton as follows: Figure 3 As shown in the diagram, the rubber ring is inserted into the circular groove 7. Then, the rubber ring is placed on the positioning post 19 and pressed into the placement groove 18. Finally, the hydraulic press 6 can be started by the controller to push the upper mold 3 downward. When the upper mold 3 contacts the lower mold 2, the upper mold 3 can no longer move downward. At this time, the output shaft of the hydraulic press 6 continues to extend, which will push the pressure block 10 downward, thereby pushing the metal skeleton out of the circular groove 7 and pressing it together with the rubber ring, thus realizing the pressing of the bearing seal ring skeleton.

[0033] When the pressure block 10 moves downward, the ball bearing 11 rolls in the spiral groove 12. At this time, the one-way bearing 9 can rotate normally, ensuring that the pressure block 10 can move downward normally. When the metal skeleton is pressed and installed, the output shaft of the hydraulic press 6 moves upward, and the pressure block 10 moves upward. The ball bearing 11 will then reverse in the spiral groove 12. At this time, since the one-way bearing 9 is locked and cannot rotate, the pressure block 10 cannot rotate, thus preventing the ball bearing 11 from rotating in the spiral groove 12. The upper mold 3 is lifted and reset by the ball bearing 11 pressing the inner wall of the spiral groove 12.

[0034] Since the pressure block 10 does not move upward during reset, the metal skeleton in the circular groove 7 is always pressed tightly by the pressure block 10, while the bottom metal skeleton is blocked by the limiting member 8 and cannot slide down. Therefore, when pressing the metal skeleton into the rubber ring next time, after the upper die 3 and the lower die 2 come into contact, the bottom metal skeleton can be pressed directly into the rubber ring. This can effectively prevent the pressure block 10 from resetting in the circular groove 7 and causing empty stroke during the next metal skeleton pressing, which affects the pressing efficiency, thereby further improving the production efficiency of the bearing seal ring skeleton.

[0035] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the limiting member 8 includes a top block 81 and a compression spring 82. The bottom of the side wall of the circular groove 7 is provided with an installation groove 13. The top block 81 is slidably connected in the installation groove 13. The compression spring 82 is fixedly connected between the top block 81 and the installation groove 13. The compression spring 82 can be used to push the top block 81 to abut against the metal frame, thereby clamping the metal frame and preventing it from falling out of the circular groove 7 and affecting the production of the bearing seal ring frame.

[0036] In a further preferred embodiment of this utility model, such as Figure 3 As shown, by machining a spherical surface 14 on one side of the top block 81 that extends out of the mounting groove 13, the bottom metal skeleton can be squeezed out of the circular groove 7, and when the metal skeleton at the next level slides down, the top block 81 can be pressed into the mounting groove 13 by squeezing the spherical surface 14. This can prevent the top block 81 from jamming the metal skeleton and affecting the production of the bearing seal ring skeleton.

[0037] By fixing friction rubber to the spherical surface 14, the friction force can be increased when the top block 81 abuts against the metal frame, thereby increasing the support force on the metal frame, making the anti-detachment performance of the metal frame better, and further preventing the metal frame from naturally detaching from the circular groove 7.

[0038] In a further preferred embodiment of this utility model, such as Figure 2 As shown, since the pressure block 10 can only move downwards and not upwards within the circular groove 7, the metal skeleton within the circular groove 7 cannot be replenished after it is used up, affecting the production of the bearing seal ring skeleton. Therefore, the press-fit upper mold 3 is mainly composed of a positioning plate 31 and a sleeve 32, and in Figure 2 As can be seen, a positioning key is connected to the inner wall of the positioning plate 31, and a sliding groove for the positioning key to slide is opened on the side wall of the output shaft. Therefore, the positioning plate 31 is slidably connected to the output shaft of the hydraulic press 6, and the sleeve 32 is rotatably connected to the output shaft of the hydraulic press 6. The top of the sleeve 32 is connected to the positioning plate 31 through the positioning member 15. At this time, the pressure block 10 can be moved upward in the circular groove 7 by rotating the sleeve 32, thereby realizing the reset of the pressure block 10.

[0039] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the positioning component 15 includes a positioning block 151 and a support spring 152. The top of the sleeve 32 is vertically downward-facing and has a receiving groove 16. The positioning block 151 is slidably connected in the receiving groove 16. The support spring 152 is fixedly connected between the bottom of the positioning block 151 and the receiving groove 16. The bottom of the positioning plate 31 has a positioning groove 17 that engages with the positioning block 151. After the sleeve 32 rotates, the positioning block 151 can be engaged in the positioning groove 17 to achieve positioning. This ensures that after the sleeve 32 rotates to reset the pressure block 10, the sleeve 32 and the pressure block 10 can maintain a stable connection. This prevents the sleeve 32 from loosening and rotating when the upper mold 3 is reset, causing the pressure block 10 to move upward. This further ensures the stability of the upper mold 3 in use.

[0040] The implementation principle of the above embodiment is as follows: the metal skeleton is installed into the circular groove 7, and then the rubber ring is placed in the placement groove 18. Then, the hydraulic press 6 is started to push the upper pressing mold 3 down to approach the lower pressing mold 2, thereby pressing the metal skeleton in the circular groove 7 into the rubber ring, which can realize the continuous and efficient production of bearing sealing ring skeleton.

[0041] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
